DUMPING-WAGON.

Specification of Letters Patent.

Patented July 4, 1911.

Application filed April 19, 1910. Serial No. 556,411.

To all whom it may concern:

Be it known that I, WILBUR HUNTER Soon, a subject of the King of Great Britain, and resident of No. 366 Bank street, in the city of Ottawa, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

The invention relates to improvements in dumping wagons, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel arrangement and construction of parts, whereby a wagon-box having an opening in the under side thereof is fitted with a bottom-board supported by suitable swing levers, and having a locking attachmentloperatively controlled from said levers.

The objects of the invention are to devise a dumping wagon which can be readily operated by the driver from the seat, will be of simple, strong and durable construction, and which will be held in its closed position to prevent premature dumping.

In the drawings, Figure 1 is a side elevation of the dumping wagon with the bottomboard closed firmly over the box opening. Fig. 2 is a side elevation of the wagon from the opposite side to that shown in Fig. 1, with the locking attachment of the bottomboard released. Fig. 3 is a side elevation of the dumping wagon as shown in Fig. 1, with the bottom-board swung from under the box opening. Fig. 1 is an end view of the dumping wagon looking from the rear.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the wagon box, preferably hopper-shaped as shown, and supported by the rear and front wheels 2 and 3 respectively. The rear wheels 2 are shown as supported on the stud axles 1 se cured to a suitable side plate 5, said plate being firmly bolted to the side of the wagon box 1.

6 is the bottom-board of the wagon box closing the open under side thereof.

7 are swing levers pivotally secured at their upper ends to the box 1 at 8, and pivotally secured at their lower ends to the bottom-board 6 at 9.

10 are fulcrum levers shown in the accompanying drawings as fulcrumed on the axle 4, though it'must be understood that said levers may be fulcrumed or pivotally supported from the wagon box 1 at any desired place. The levers 10 at the lower ends thereof have the slots 11 through which the pins 12 from the bottom-board 6 extend.-

13 are hooks pivotally secured to the bottom-board 6 by the pins 12, and connected toward their hooked ends by the links 14: with the levers 10.

15 are lugs secured to the back of the wagon-box 1 adjacent to the bottom thereof, and onto which the hooks 13 are caught when the bottom-board 6 is closed under the opening in the under side of the wagon box.

19 is a hand lever fixedly mounted on the shaft 20 extending from side to side of the wagon immediately below the seat and having the crank lever 21 fixedly secured thereto on the far side of the wagon as shown in Fig. 2.

22 are connecting bars pivotally joining the lower ends of the hand lever 19 and the crank lever 21 with the upper ends of the fulcrum levers 10, said connecting bars preferably being elbowed at 23 to clear the upper end of the swing levers 7.

When the bottom-board 6 is closed over the opening in the under side of the wagonbox, the hooks 13 are caught over the lugs 15, as above described, thereby firmly holding the bottom-board 6 in place, and forming with the swing bars 7 a very strong and efficient support for the bottom-board 6.

lVhen it is desired to dump the load from the cart, it is only necessary for the driver to push the hand lever 19 forward, and through the connection of the connecting bars 22 with the fulcrum levers 10, the lower ends of said fulcrum levers are swung forward. Before the fulcrum levers 10 commence to carry the bottomboards 6 forward to dump the load, the hooks 13 must be removed from engagement with the lugs 15. This action is provided for by the slots 11 at the lower end of the fulcrum levers 10,

which allow them to move the length of said slots 11 on the pins 12, and as the said levers 10 are connected by the link 14: with the hooks 13, said hooks are drawn from engagement with the lugs 15, as shown in Fig. 2, following which the bottom-board 6 is carried from under the opening in the wagon box, allowing the load to be dumped therefrom, as shown in Fig. 3. In returning the bottom-boards 6, the hand lever 19 is drawn back, and consequently the lower end of the fulcrum levers 10, the movement thereof always tending to force the hooks 13 in the same direction, and when the said hooks meet the lugs 15 they are forced into engagement therewith, and the bottom-board 6 firmly held in its closed position.

The connection of the shaft 20 with the hand lever 19 and the crank lever 21 transmits the action of the hand lever to the connecting bars and fulcrum levers on both sides of the cart, and consequently the hooks on both sides are positively placed in engagement with the lugs and the bottomboard 6 at all times carried with equal support on both sides of the wagon-box, thereby preventing any tendency of the bottom board 6 to sag on one side or the other.

It will be readily understood that the position of the points at which both the swing levers 7 and the fulcrum levers 10 are piv otally supported may be altered to some extent to suit the shape of the wagon-box, that is, a difference in the length of said levers will alter the are through which the front and back of the bottom-board swings. In the drawings, the swing levers are made of sufiicient length to swing the bottomboard gradually upward at the front end thereof, whereas the lower sections of the fulcrum levers 10 are made shorter, so that the back of the bottom-board when swinging to its open position drops slightly, thereby facilitating the action of swinging the bottomboard to its open position, as the back of said bottom-board while opening, practically drops away from the load, which is very readily dumped.

It will be readily understood that the arrangement of the running gear is quite optional, and the front supporting wheels may be discarded, using only the one pair of wheels as in a cart, or the rear wheels may be located at the extreme rear of the wagon, in which case, as also in the form shown in the drawings, the axle if desired may be run from side to side of the cart. It will also be understood that the bottom-board may be duplicated, making two parts to cover one large opening, both having lever connections with a hand-operating lever, as shown in the drawings, the one front bottom-board swinging to the front of the wagon, and the bottom-board at the rear swinging to the back of the wagon, and if desired, a partition may be made, dividing the large opening into two compartments, the opening in each compartment having a separate bottom-board.
